Zalman says NB47J Northbridge cooler fits A8N-SLI

[sxr7171]

Skinner, it looks like I might just have to turn the sink around. I used the Zalman paste instead of AS5 because I remember readin someone around here (on AT) said they got better results with it (I may have misread though). Then I found this article: http://www.neotec.pl/page.php?id=21 Looks Like I'll be replacing that Zalman grease.

The AS5 works well, and I can say that reliably say my system is very stable.

Hello everyone - new one here

Nice link sxr7171 - I was really suprised to read something here in polish. Where are You from???
I'm also using NB47J with Zalman paste, works great as for now... Heatsink is gettig a little warm, but still OK in my opinion. 12 cm Thermalkake fan does great job. And no 8K RPM bastard in my case (some people say it is silent, but my was rattling LOUD

Not even one problem with A8N - instalation smooth, stable, no OC for now - it's fast for me (comparing to my old PIII). Really happy user here!

Well, the funny thing is that I can't read a word of that review I just linked to it from another post. I think the graphs pretty much explained everything.

My NB fan was like a lawnmower at best.

I hoped - same polish guy there

Anyway thanks for the link :beer:. I was trying to avoid AS5 because of its electrical conductivity, but after reading this article and Skinner saying it's OK, I don't. It's a shame that Zalman doesn't include better thermal paste with NB47... Anybody know some good thermal compound without electircal conductivity?

 

[imported_Skinner]

Zalman does include Arctic Ceramique with the VF700, because they have the margin to do so. You'll never find it on a sink with that low a price tag - sorry.

I didn't want to give the impression that conductivity between heat pipe and the NB47J is good - I just don't know the implications of letting them touch. AS5 is a fine paste, I don't think they would be able to sell something like that with it being conductive....

Thanks,
Skinner

You have a point there. AS5 isn't exactly conductive but capacitive, but they warn that metal shavings flying around the case can quickly make the stuff conductive. Your post sort of scares me since the metal of the VGA core is touching the sink which touches the heatpipes which touches the NB sink and touches the back HS of the VGA cooler. Luckily there is that plastic sticker they give you for the rear heatsink.

Incidentally they included el cheapo Zalman paste with the HP80-D.

 

[imported_Skinner]

My bad - The VF700 came with crap paste too. I got the tubes confused between the SwiftTech MCX6400-V package and my VGA Cooler, of which it came with the Arctic Céramique.

Sorry for the confusion.

I'm new to thermal paste etc,.. it's been a long time since I've built my own machine.

I plan on using an NB47J on my NB.. what is the verdict on the best thermal paste to use? I currently have a tube of artic silver 5, but from this thread, not sure if that's a good idea or not. Is it better to use AS ceramique instead?

I'm going to replace Zalman paste with AS Ceramique
According to link posted by sxr7171 it's not much worst than AS5.
I still don't believe that something that "Contains 99.9% pure silver" may be not eletrical conductive at all :light:
And don't want any circuit on the surface of brand new NF4-Sli...

 

[SailorGuy]

Well, I changed out the cooling on this system and what a difference. Thanks for all the advice on the VGA and Chipset cooler. I have no interference problems between video and chipset cooler.

Temps - just banging around - all fans at slow speed, no front fan running
CPU - 36
System - 37
GPU - 39

I need to really load it up to see what happens.

I'm a bit lost..what is wrong with it being "electrically conductive"? So what is AS 5 supposed to be used for then? Is it safe to use on my CPU?

May be related for some of you. I left the stock HS in. I just changed my chipset fan with a 4cm/4200rpm fan. REALLY easy (no need to take out the mobo), and it runs at about 3750rpm. I can't hear it, and the temp actualy dropped from what it was with the stock one running at 8800rpm.
Really happy with it.

NiceGuy, I was planning to do this, so I went out and bought a 40mm fan.
However, I had no way to attach it because the little screws that hold the default cover on are not long enough, and I couldnt find andy screws anywhere that were thin enough to work on the default heatsink. What did you use?

What fan did you end up using?

 

[sxr7171]

Hey Skinner, I ended up doing it!

I actually ended up changing the direction of the heatsink and it looks a lot better. They are almost miles away compared to how the heatpipes and the NB47 were before. It was a bit a work actually but ultimately worth it in the end. I have no touching of heatpipe and heatsink and, my MB temps (in ASUS probe) are better by 5-6C thanks in part to replacing the Zalman paste with AS5 and the better airflow. I also redid my wiring and altogether the better airflow in my case due to better wire routing and changing the direction of the heatsink has reduced my CPU temps by about 1C (idle and load) also. It was a win-win change.

EDIT: I forgot the best difference! My VGA temp doesn't even go above 60C anymore! It used to go up to 78C in a matter of seconds when a 3D program (http://www.daionet.gr.jp/~masa/rthdribl/) was launched. My VGA overclock has gotten better and I while I used to see some artifacting on higher overclocks I don't anymore. This is much better!

One other thing as an aside the actual NB47 is hotter to the touch now and that's actually a good thing as it means the heatsink is actually working (removing heat from the chip).

SRX: What video card are you using? I was planning on using the Zalman VF700 on my eVage 6600GTI PCIe, but if I can use their heatpipe instead, I woudl prefer to do that obviously.

 

[Speedo]

Hi! This is my sollution, when building a system for a friend where low noise is of high priority (system is being used in music production). I used the NB47J and a Zalman FB165(80mm) which is very quiet with the supplied resistor. I made some modifications to the "arm", so that it blows more directly towards the chipset. I could also just unplug the fan to the X300 videocard, which made for a very quiet system. I'm actually using the boxed HSF in this sytem, and with Q-fan enabled the CPU still runs at around 39c and the only thing you hear now from the system is the 120mm PSU fan. The system looped 3DMark all night at 160FSB with no stability problems at all. My friend was very satisfied...

For my personal system I'm building soon, I will use similar components, but an XP-120 with Panaflo and a Leadtek 6600GT card.

Hi Shrpnsmart- I couldn't be bothered messing around finding screws/washers (I think they are 2milli), so I just used 2 twist ties to secure 2 corners to the HS pushpins. Works perfectly. It's so small that it doesn't really need mounting hardware like a bigger fan might. BTW, I took all the junk off the HS, inluding the tin cover, to help airflow.
Runestone- I bought an Ainex/Adda fan. 4cm x 1cm, rated at 4200rpm, 4.7CFM, below 14dB, 50,000 hours.

Now that i think about it, going heatpipe might not be that great of an idea.. I've read reviews where the ATI 9800 PRO is at >60 degrees in fanless mode, but when you add the optional zalman fan to teh configuration, it <40 degrees.

If I have to add a fan to this setup, there isn't much value of going heatpipe is there? I may as well just stick with my Zalman VF700 fan configuration.

I guess not really if you already have a VF700. I would have gotten a VF700 if for whatever reason a ZM80D didn't fit. The fan they give you is really quiet at 7v but pretty loud at 12v.

Hej tmchow

Reading this Article, by simple closing some resistor pads on the surface of NF4-Ultra with conductive paint they converted the Ultra to SLI. I just don't want to try what happend when you close paths between 2 separate resistors... You have some plastic isolation on chipset with hole for the chipset core, so I understand it that way you should avoid contacting anything conductive with that resistors. But silver paste (or silver powder that comes from the paste after some time) can easly come under this plastic cover and... (I hope I'm wrong, but as I said, I don't want to try )
AS5 is a great paste for CPUs like Athlon64 which have nice, plain and isolated surface without any metal elements coming from.

Oh i see.. so my plan is going to be:

AS5 for CPU
AS Ceramique for chipset on my NB47J.

thanks!

No comments on my sollution?
http://www.upsweden.com/files/a8n-passive.jpg

On my own system I'm thinking of finding a way to attach the arm holding the fan from the other side (somewhere around the drivebays) instead so there won't be so much occupied space around the slots.
